Data Bus ARINC429, Arinc629 and MIL STD 1553B |

Описание: An integrated avionics system consists of various subsystems and components that need to communicate with each other in order to share information. Up until the early 1970’s, many avionic systems were largely analog implementations using syncho and potentiometer outputs and inputs with required point-to-point wiring between various sensors and their dedicated cockpit instruments. As such, there were many large and heavy wiring bundles with point-to-point wiring, in addition to reliability problems due to intermittent connector pin failures.

In order to reduce aircraft weight and increase reliability, it became necessary to decrease the amount of aircraft wiring and connectors. Therefore, avionics system designers began using Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs) with serial point-to-point digital data buses requiring only two twisted pairs of wires connecting single data transmitters (sources) and single data receivers (sinks). These data buses evolved into single-source with multiple-sink buses, such as ARINC 429, and multiplesource with multiple sinks buses, such as ARINC 629 and its military equivalent, MIL-STD-1553B.

Time-Division Multiplexing (TDM) enabled different forms of information to be transmitted through one communication system. A multiplexer was used to sample input data sequentially and then stagger the different data samples in time to form a composite digital pulse train. By knowing the clock time and address of the various signals, a de-multiplexer at the receiving end would decode and distribute the individual signals. The following sections will discuss several popular military and commercial aircraft digital data buses, beginning with MIL-STD-1553B.
